ROLLER-SHADE FIXI'U'RE;

Application filed. Aprilf 10, 1922. Serial No. 551,225.

To all: whom it'may concern:

Be it known that I, FRANK M. BONHEIM, a citizen of. the United States, residing in the city of. St. Louis and State of Missouri, have invented certain new and useful Improvements in Roller-Shade Fixtures, of which the following is a specification.

My invention relates to improved shade fixtures, and, isa distinct and practical im- 0 pnovement to overcome certain important and practical objections to, and defects in, shade roller fixtures for windows of the type wherein rollers are adapted to fric-- provide a roller shade fixture which will not only hold the curtain at any adjusted position, but which will also hold the lower,

or stick end of the shade-from flopping due to gusts of wind when the window is open, from either the top or bottom.

With the-above and other objects in view,

the invention consists in the novel features of construction, arrangement and combination of parts hereinafter more fully describedand finally pointed out in the claims heretoappended.

Referring to the accompanying drawings forming --a part of-this specification, wherein like characters of. reference denote similar parts throughout the several views:

Fig. 1, is a front elevation of a portion of a window frame, ashade and a holding device therefor embodying my invention.

Fig. 2, is a plan view showing the hold- 4 ing device in frictional contact with the window frame tohold the shade in any adjusted position against the pull of the shade-roller.

Fig. 3, is a detail showing one of the holding devices disengaged from the window frame.

Fig. i, is a detail showing the shade holding roller partly in section.

In the illustrative embodiment of" my present invention shown in the drawings, the lower fold 1 of the shade, or curtain 2 is provided withv a transversely disposed shade stick8'. The upper-end of theshade 2"is securedito a suitable constantly acting spring-roller 4- which. is. mounted at either 6 M end by mean-s of suitable shade supporting fixtures. 5, which are suitably fixed to the inner opposed faces 6' of thewindow frame In carrying out the further aim of my invention, I provide each-end of the shade stick 3 with a fixture 18' whichis. suitably v. fixed to the shade stick and which isprm vided; with. the extended spaced; roller supporting. arms 9. Eccentrica-lly mounted-between the arms 9 of each-fixture 8 is a suitableshadeiholding roller 10.. which, iszmounted upon. a shaft'll surrounded by means of a coiled spring 12 having the extended ends, or arms, desigmated"1 3. and 14. Arm 13 of the spring 12 engages astop 15 upon one-of the arms9 of each fixture 8 and the 211 mm engages. a'stop l6zcarriedby one of the side faces of each eccentric roller 10 against which the arm 13 presses to hold the eccentric rollers 10 in their outwardmost position, so as to cause the peripheral face thereof to frictionally engage the inner faces 6 of the .windo-w frame 7 thereby holding the roller shade 2: at any adjusted position and prevent flopping of the lower end of shadeQ, as is manifest I Connected. to each, eccentrically-..mount,ed shade holding roller- 10, is a suitable cord 17, or-its equivalent. These two. cords 17 lead inwardly toward each. other above the shadeestick to a; point approximately midway the ends ofthe shade stick 3, then they are directed inwardly-'1 and. downwardly through converging passages. 18 in the 95 shade-stick and. unit-e, as. at 19, to be con: tinued downwardly in the form of a. single shade-cord 20 provided atits. lower endwith a suitable pull ring 21. v v

' It is. evident that when, it is desired'to adjust the curtain. to. a new. position, or

position is reached. in either direction, up or down, pressure is quickly released upon the ring 21, and the coiled springs 12 will quickly rotate the eccentric mounted. roller outwardly for peripheral frictional contact with the inner faces 6 of the window frame 7 for holding the shade firmly in the adjusted position.

From the foregoing description, it is evident that I provide a shade fixture which is easily applied to the shade-stick of a curtain shade and which will positively hold the shade in any adjusted position against the spring pull of a shade roller as well as hold the shade from flopping when the shade is down and the windows are open from either above or below.

The many advantages of the herein described invention will readily suggest them selves to those skilled in the art to which it appertains.

I do not desire to be understood as limiting myself to the exact details of construcof my invention and the terms of the following claims, hence I wish it to be understood that I reserve the right to make any such changes, or modifications as may fairly fall within the scope of the appended claims when fairly construed.

hat I claim is:

1. In a window shaft holding structure, a shade-stick, a bifurcated fixture fixed to each end of the shade-stick and extending he end the ends thereof a. sin le eccentrically mounted shade holding roller rotatably supported by the li ifurcated end of each fixture, resilient means engaging the roller and said fixture for normally holding the peripheral face of each shade holding roller in frictional contact with the inner face of a window frameto hold the shadestick in any adjusted position and means for partially rotating the shade holding rollers against the spring action thereof for releasing the shade holding rollers from frictional contact with the inner face of the window frame to permit the raising or lowering of the window shade.

2. In a window shade structure, a shadestick having converged openings, a bifurcated fixture fixed to each end of the shadestick and extending beyond the ends there of, a single eecentrically mounted shade holding roller rotatably supported by the bifurcated end of each fixture, resilient means engaging both the fixture and roller for normally holding the peripheral face of each shade holding roller in frictional contact with the inner face of a window frame to hold the shade in any adjusted position, and a pull cord connected to the peripheral face of each shade holding roller, the inner ends of said cords passing through the converging openings in the shade-stick and terminating in a single pull-cord which may be actuated for releasing the shade holding rollers from frictional contact with the inner frace of the window frame to permit supporting pin coiled spring, a stop lugfixed to one side of each roller for engage the coiled spring for normally holding each ment with the opposite extended end of shade holding roller. in outwardly directed frictional contact with the inner faces of a vindow frame to hold the window shade at any adjusted elevation, a pull cord connected to the peripheral face of each shade holding roller, the. inner end of said .pull

cords passing through the converging open-.

ings of the shade-stick and terminating in a single pull cord to be actuated for releasing the shade holding rollers from frictional contact with the inner face of. the window frame to permit raisingor lowering of the window shade to a new position.

4. In a window shade holding structure,

a shade-stick having a pair. of converging openings with the upper and lower faces of the shade-stick, a bifurcated fixture fixed to and extending from each end of the shade pin carried by the bifurcated end of each bifurcated fixture. a coiled spring encircling said pin, a shade holding stick. a cross roller eccentrically and rotatably mounted upon said spring, a lug carried by the bifurcated fixture for engagement with one end of the coiled spring, alug carried by the roller for engagen'ient with the opposite end.

of the coiled spring, a bifurcatedcord having its outer bifurcated ends connectedto the peripheral face of each shade holding roller and having its inner end directed through the converging openings ofthe shade stick.

In testimony whereof, I. have hereuntosigned my name to the specification.
